Abstract

L'invention concerne un stimulateur mécanique qui évoque une perception auditive en produisant directement des ondes de déplacement du fluide présent dans un canal semi-circulaire du destinataire. Le stimulateur mécanique comprend une unité de traitement acoustique configurée pour traiter un signal acoustique reçu, et un système implantable de stimulation qui comprend : une prothèse d'étrier dont une première extrémité est configurée pour être placée en butée contre une ouverture ménagée dans le canal semi-circulaire, un actionneur configuré pour recevoir des signaux électriques qui représentent le signal acoustique traité et configuré pour vibrer en réponse aux signaux électriques et un dispositif d'accouplement qui relie l'actionneur à la prothèse d'étrier de telle sorte que les vibrations de l'actionneur entraînent la formation dans le canal semi-circulaire du destinataire d'ondes de déplacement de fluide qui évoquent une perception auditive du signal acoustique reçu.
